Description
Technical field
The present invention relates to automobile technical field, more particularly to a kind of safety belt detection device.
Background technology
Safety belt can protect driver and passenger when there is car accident, but often many drivers dislike trouble and
Safety belt buckling free, the prior art detects in seat buckle whether engage safety belt buckle by way of being buckled and detecting, so as to sentence
It is disconnected whether wear safety belt, but this mode is easily cheated by driver, and such as more commonly used is by the only single of purchase
Only buckle is inserted on seat buckle, so as to cheat warning device.
The content of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of safety belt detection devices, pacify for detecting
The use state of full band, this safety belt detection device can utmostly reduce the detection fraud of safety belt, and testing result is accurate
Really.
To achieve these goals, the technical solution adopted by the present invention is：A kind of safety belt detection device, including seat card
Button, controller and instrument warning device；It is set in seat buckle there are one metal contact switch, when detecting safety belt buckle
Buckle just sends a signal to controller after buckling；It further includes the strained detection device being arranged in safety belt, be arranged on seat
On signal supervisory instrument, the stress detection device for detect safety belt stress, the signal supervisory instrument is used for
Detect the pull-out length of safety belt；The strained detection device, signal supervisory instrument are by the data transmission detected to controlling
In device, the controller pulls out length three's number according to the signal of the metal contact switch received, by force signal, safety belt
According to multilevel iudge, whether alarm so as to control instrument warning device.
The controller pulled out by the signal of metal contact switch, by force signal, safety belt length three data with it is pre-
If data comparison, only when three signals are consistent with respective default signal, alarming instrument device is not just alarmed, otherwise
Controller control instrument warning device is alarmed.
The signal supervisory instrument is code reader, one group of bar code is set on safety belt, code reader is according to scanning
Bar code obtains the tensile elongation of safety belt.
The strained detection device uses patch type pressure sensor.
The strained detection device is arranged at first distance of safety belt buckle one end.
The patch type pressure sensor is connected with power conductive sheet, and power conductive sheet is the strip being of same size with safety belt
Shape plastic sheet, the plastic sheet are arranged on safety belt and the one side of human contact, and pressure sensor is arranged in safety belt.Institute
The controller stated is realized using car body controller.
The advantage of the invention is that：Signal is fastened by the stress of safety belt, the pull-out length of safety belt, buckle to judge
Whether normal wear safety belt, the wearing of safety belt fraud is reduced with this, accurately for seatbelt wearing provides warning information.
Description of the drawings
Below to each width attached drawing of description of the invention expression content and figure in mark be briefly described：
Fig. 1 is safety belt detection structure schematic diagram of the present invention.
Specific embodiment
Below against attached drawing, by the description to optimum embodiment, the specific embodiment of the present invention is made further detailed
Thin explanation.
Such as Fig. 1, a kind of safety belt detection device, including seat buckle, controller and instrument warning device；It is buckled in seat
It inside sets there are one metal contact switch, controller is just sent a signal to after the buckle for detecting safety belt buckle is buckled；Also
Including strained detection device, the signal supervisory instrument of setting on the seat being arranged in safety belt, stress detection device is used for
Detection safety belt stress, signal supervisory instrument are used to detect the pull-out length of safety belt；Strained detection device, signal supervisory instrument
By the data transmission detected into controller, controller according to the signal of the metal contact switch received, by force signal, peace
The full multilevel iudge with pull-out length three's data, so as to which whether control instrument warning device alarms.
Controller pulls out length three data and default number by the signal of metal contact switch, by force signal, safety belt
According to comparison, only when three signals are consistent with respective default signal, alarming instrument device is not just alarmed, otherwise controller
Control instrument warning device is alarmed.Only length is pulled out in metal contact switch closure, safety belt stress, safety belt reach default
Normal safe wearing strip length in the range of, when three's condition all meets, be judged as normal wear safety belt at this time, do not send out
Go out alarm, if any of which one is unsatisfactory for condition, in the presence of no safety belt may be matched somebody with somebody, send alarm signal at this time.Peace
The belt length data that full band is normally worn can be set according to statistics.Stress refers to that in seatbelt wearing human body is with pacifying
It is complete that with safety belt is close to, and safety is with certain elasticity with contact, then when wearing, safety belt can with human body it
Between have faint pressure data, this pressure is insignificant for human body, but can be used to detect whether to exist and wear.
The detection of the pull-out length of safety belt can be passed through by setting one group of bar code on safety belt in safety belt
Place set bar code code reader, for the barcode signal of safety belt to be sent to controller, determined according to barcode signal
The pull-out length of safety belt.
Strained detection device uses patch type pressure sensor.Strained detection device is arranged on apart from safety belt buckle one end
The first distance at.What pressure-detecting device can be generally arranged on to safety belt can detect people and any of safety belt pressure
Position can will be arranged in the belt position apart from the first distance of safety belt buckle to preferably detect, this first away from
From that can count setting in advance, it is usually that this belt position is corresponded at the shoulder of human body that the first distance of safety belt, which meets, is led to
One value range of setting can be settled accounts by crossing statistics, so that it is determined that the position of the first distance set.
Patch type pressure sensor is connected with power conductive sheet, and power conductive sheet is the strip plastics being of same size with safety belt
Piece, plastic sheet are arranged on safety belt and the one side of human contact, and pressure sensor is arranged in safety belt.So worn in detection
During safety belt, the pressure between people and plastic sheet is transferred to the sensing chip one side of pressure sensor by plastic sheet, is passed by pressure
The people and the pressure data of plastic sheet that the sensing chip sensing plastic sheet of sensor transmits, since plastic sheet is set and safe bandwidth phase
Same strip, can like this obtain the stress of bigger or when there is security incident, can increase the stress surface of human body
Product, reduce setting pressure sensor patch area it is small may caused by damage to human body.
Obviously present invention specific implementation is not subject to the restrictions described above, as long as employing the methodology and skill of the present invention
The improvement for the various unsubstantialities that art scheme carries out, within protection scope of the present invention.
